How to Water and Fertilize a Bottlebrush Tree
- 1). Water the bottlebrush tree daily during the first week after planting. Give the plant enough water to saturate the roots, but take care not to pool the water around the base of the tree in the process.
- 2). Reduce the rate of watering to two or three times weekly for two to four weeks after the first week. As with the first week, thoroughly saturate the roots of the tree with the water without pooling.
- 3). Stop watering regularly after the initial planting process. After the initial planting, the tree needs little water and can gain all that's required through natural rainfall. Overwatering will make the tree prone to fungus.
- 4). Fertilize the tree upon initial planting and then two to four times a year by sprinkling 1 to 3 pounds of a low-phosphorous fertilizer over the root system. For best results, fertilize the trees at the beginning of the spring, summer and fall.
